In this George Pal Puppetoon (production number U5-6), John Henry (voice of Rex Ingram), legendary figure of American folklore, goes to work for the C.& O. Railroad, which, shortly thereafter, buys an automatic steel-driving engine, called the Inky-Poo. John Henry matches his strength against the Inky-Poo, saying that any man can beat a machine because a man has a mind. John Henry wins, but drops at the finish, never to rise again. The choral music background is by the Luvenia Nash Singers.
